Inngest — design system & UI screens

Dev Tools · 1 screen · 11 sections · inngest.com

Near-black landing for the durable-execution platform Inngest, anchored by a giant Swiss-grotesk hero where the top line "UNBREAKABLE AGENTS." is set in solid white and the second line "INVISIBLE INFRA." is rendered as an outline/stencil treatment, paired with a scattered code-particle field and a tiny step.run()/waitForEvent()/invoke() legend. The signature device is the recurring product-screenshot motif — a real "Runs" dashboard table, a multi-series "Total runs throughput" line chart, and an interactive BEFORE/AFTER architecture diagram with an electric-blue draggable divider — used as proof throughout. An orange "START BUILDING" CTA and orange accent rules punctuate an otherwise monochrome, all-caps section-header system.

Decoded design system

Inngest's decoded design system: background #0C0A09, text #64748B, accent #FB5536, link #1E293B, primary #FB5536; type scale h1 115px / h2 64px / body 18px; 4px spacing base; 6px base radius. The single interactive/action color is #FB5536 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#0C0A09`
surface	`#111010`
border	`#19191C`
text	`#64748B`
text_muted	`#424B59`
primary	`#FB5536`
accent	`#FB5536`
link	`#1E293B`
secondary	`#64748B`
button_bg	`#FB5536`
button_text	`#FFFFFF`

Using these colors

Action color #FB5536 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #FB5536 — one role, not several (the action color).
accent #FB5536 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
link #1E293B — fails contrast on the background (~1.4:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #64748B — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
